The Periodic Replacement and Reconditioning Eliminated The sensor operates on a simple coulometric process in which oxygen in the sample gas is reduced in an electrochemical cell. Unlike conventional electrochemical oxygen cells, the electrodes in this advanced cell are nondepleting, so they don’t undergo chemical changes as oxygen is measured. As a result, periodic cell replacement or conditioning is not required.
Parts Per Billion Oxygen Measurement For oxygen measurement in ultrapure gas applications, an ultralow range sensor that is sensitive to less than five ppb is available. The sensor is equipped with VCR fittings to ensure system cleanliness and integrity.
Withstands Acid Gases For most applications where acid gas constituents are present, the patented STAB-EL™ electrolyte option eliminates the need for troublesome gas scrubbing equipment by permitting direct exposure of the cell to the gas stream. These cells have a reputation for reliability in applications that are too difficult for most other oxygen sensors.
Sensor Placement The basic sensor is available separately. However, for Type 4 applications requiring indoor/outdoor water- and dust-tight enclosures, an R4 sensor is available that is housed in a weatherproof enclosure with integral mounting flanges. For hazardous (classified) locations, an R7 sensor is available. It is housed in an explosion-proof, aluminum electrical box that is rated for hydrogen service, and can be used in Class I, Groups B,C&D; Class II, Groups E,F&G; and Class III, hazardous locations.
